Possible bug in WordPress 6.6

Hi folks:
in case you notice this; we have seen a bug in latest edition of WordPress which causes the category selector on post edit page to show entire list of all categories vs just a selection you can scroll throuugh. Seems irrelevant as to theme, and unrelated to our sites running php 7.4x or 8.2x.

The fix for us at the moment vs rolling back to 6.5.5, was to install
the Admin CSS MU plugin to quickly add this CSS:
div#categorydiv.postbox {
height: 600px;
}

div#category-all.tabs-panel {
height: 480px;
}

I posted a bugtrac to the WP dev team. As always, it seems with a major dot rev, WP has joined the “wait for the dot one” group. I’m expecting we’ll see a 6.6.1 or whatever soon.

Specifically this is when the Classic Editor and Classic Widgets plugins are active (which we use on all our sites, as we never use Gutenberg).
